A question about a recipe: Shrimp and Corn Tamales with Roasted Poblano Crema

I have a question about the ingredient "1 t. @ of chili powder, cumin, white pepper, thyme or mexican oregano, and kosher salt." on the recipe "Shrimp and Corn Tamales with Roasted Poblano Crema" from lorigoldsby. Do you add 1 teaspoon of each spice?
